The Ministry of the Occult (オカルト省, Okaruto-shou) is one of the leading factions in Sauville's government. It is composed of people who have strong beliefs in the existence of the supernatural, with the influential aristocrat Marquis Albert de Blois as its leader.
The Ministry's primary purpose is to research on the existence of supernatural entities, and it is also used by Marquis de Blois to search for a "secret weapon" that can be used to protect Sauville from the dangers of a suspecting incoming war.
